SolarEdge SE20K-RW00IBNM4 is a three-phase inverter with a rated output power of 20 kW, designed for commercial photovoltaic installations. The device is designed to work with SolarEdge power optimisers, enabling energy yield optimisation and system monitoring at the individual module level.

The inverter uses a fixed DC voltage architecture, allowing longer module strings to be designed. The maximum inverter efficiency is 98%. The model is suitable for installations on commercial, industrial and agricultural buildings, as well as public facilities.

The SE20K-RW00IBNM4 version is equipped with four pairs of MC4 connectors and an integrated, replaceable Type 2 DC surge protection device. This version does not include an integrated DC switch, string fuses or AC surge protection.
